If the truth of such a Divinty exists, it can in no way accept partnership.
For those who respond to Divinity —that is, the fitness to be worshipped— with thanks and worship, are the conscious and animate fruits on the highest branches of the tree of the cosmos.
If others were able to gratify and place under their obligation those conscious beings in such fashion as to make them turn away from and forget their true object of worship —Who may, indeed, be swiftly forgotten, because of his invisibility— this would be in such utter contradiction to the essence of Divinty and its sacred purposes that it could in no way be allowed.
It is for this reason that the Qur’an so repeatedly and with such vehemence refutes polytheism and threatens the polytheists with Hell-fire.
